Review the types of elements that create ionic bonds as well as the types of elements that create covalent bonds.
• N2 • CCl4 • SiO2
• AlCl3 • CaCl2 • LiBr

N2 Covalent

CCl4 Covalent

SiO2 Covalent

AlCl3 Covalent

CaCl2 Ionic

LiBr Covalent

Explanation:

With covalent bonds, there is a sharing of electron pairs between the atoms.

With ionic bonds, there is complete transfer of valence electrons between atoms. Formed by the interaction of a metal with a non-metal.

Where:

Electrons aren't transferred in covalent bonds.

Protons aren't  transferred in covalent bonds

Protons aren't shared in covalent bonds

N3-

C4+

Cl-

Si4+ = Metal

O2- = Non-metal

Al3+ = Metal

Li+ = Metal

Ca2+ = Metal

Br  1-, 1+, 5+ = Halogen

N2 = N3- and N3- Covalent

CCl4 = C4+ and Cl- x4 Covalent

SiO2 = Si4+ and O2- x 2 Metal with non metal Covalent

AlCl3 = Al3+ and Cl- x 3 Covalent Though this one is complex as to why because it seems like it should be ionic

CaCl2 = Ca2+ and Cl- x 2 Metal with non-metal Ionic

LiBr = Li+ and Br- Covalent as neither is a non-metal

a. they are both space stations

happy to

pls mark as brainliest.
